I think I'm going to go for a P226 in 9 mm. 9 mm ammo is cheaper for practice, and I don't want to invest $2000 into a custom Caspian 1911 with an external extractor (which is what I really desire in the end....god I should have kept that f$#king Para Ord P14-45 Ltd ).

That said, who sells high caps? I assume Mec-Gar is the way to go on the 10 round magazines. I'm not paying $40+ for "factory" magazines. The ten round mag I looked at seemed to be ok. The follower wasn't extra hard to push down at least.

...nope, not one bit! The only caveot is ordering from Sig, the parts aren't very expensive (about 7/ea iirc) but the shipping is outrageous some like $20! Try to get a group buy together. All my Sig mags are done this way, as it works with 228 mags as well.
